. One of thc most. ii'nportjant'objects of my invention is t o 'fnrnish'a direct cin'nmunication bctwcen thcmelting pot and thcbacking pan and cause. the molten metal to [low from the, melting pot; Ito thcbnckingpan'or re ccptacle. contaii'iing lhc 'sl\,c'l .l.,.and controlling the no: said metal, and thereby allowing the lnoltcnmctal 'f-ron the inciting pot flow, and 0c pinnped directly from the meltmg pol ntothc sa d pan. or rcccptaclc and.

onto. and over the shell therein. v.lflere'tofore the inolten metal has been dipped out of the melting pot, by means of a. ladle, and poured ovcr the shell in the pan. 7

.zAl'iothcr object is to provide means for forcing: the molten metal from the melting pot into the pan or receptacle containing the shll. v

Astil l'fnrthcr object is to provide a device which is simple,i 'nexpensivc and (1 11-- rabloin construction and easy .to operate.

Theinventipn consists in theseveral features and combinstio features as hereinaftgcrmore. {specifically described-y and. claimed. I g 1 Referring to tho.drawingsr Figurc 1 is. a ccntral longitudinal section Figw2-is a similar View, showing a modified form of constnnctionl Int-he drawings 1., indicates the furnace, 2 the melting pot prpvidediwith-s flange 3, which. scats. on a l 910f thcifurnacef A pump-5, having 'a-"cylindcr-G, is seated and secured ,on a bracket. 7, at one :SldQ-jflt; the furnace, and is' proVideclwitl i one end s cd-hzan 1 i. of the melting pot, and the; other end in the side of the pump cylinder, through which the molten metal flows fromthe melting not into the pump cylinder, 9 being an outf3 t pipe, one end inserted in and secured to and more especially to l'mcking them under l the 11111111.; cyli'l'idcr and the opposite end 11cstrictcd" son'iewhat to form a nipple or nj'oz- 210 and inscrttcdand scated inn holc 9",in' thc lmcking pan and passing through an" a 'ycrtinfcfl'fl in the Wall of the tnrnaccl' Tl' e pninp' is provided with. a piston '11 having" its lowcr' portion cut oil at. an 'anglsas, at 12, a. piston 'rod 13, and it i'lllilCllG '14, pivoted to a bracket 15 extending fronrthd upper edge of the melting pot, said handle being provided with an'longated slot 16 to rcccivc a pin 16 which connects the piston rod and lnini'llc. A; suitable backing" stand 1?, is novidcd, having leveling screws 18 and lock nuts 19 therefor.

The lmc ing pan 20 seated on and leveled by i'l li'zans of'thc scit 1S, and its cover or closin'e 31, which in this instance is sho vn j as the ilatcnof a press 22, is providedwithfg'ro avcnt Qilnncl plis.i'g24-,jfor closing ss'id ,vcnt operated by a handle 26, the hand Whcel of the press secured to thonppcr end of 2i clamping s1-ewi27,' which is carried by the pivoted yoltc 2S. Itl'BG n'ill' be seen that by the nsc'of the pivoted yoke the clamping screw,'hand Wheel and: 'yokecan be swung out: of thc'way when not in use) The. platen 21, is preferably placed on rcmovcdfrom the hacking; pan and inserted int-o the. molten nictal in the. fnrnac by means of a block and tackle 29-, having in hook 80, which engages with links 3.1,"pi. otcd to the top of the platen. A blast his; is provided through which. aif' isfor ccdihjf mca ns of a suitable h'l'oivcr, not shown, 'f thgpnrpose of cooling the backing n.

' Referring to the modiflc at io1 I '1 ates the melting. pot,'2 the furnac 3f backing stand, 4 ,the backing pan suppo on screws 5, end provided with a cove closure 6%, which in this instance is the pl of the press ,7? wh-i ch. is provided with pivoted yoke .83 haying a clamping scge and h-grndnyhecl lm.Q The pump in this. case; sd fcirislsdi w th y'li 11813891111? the bottom'j of andlinside the melting pot and has an inlet. 12 leadingfromthe melting pot into said cylinder, and outlet pipe 13* leading from the cylinder into the backing pa'n. 143* is the piston of the pump which lipv is provided witha piston rod 15 and a hendle 16 for operating said piston.

The operation 1.5 35 .follows :--The electro type shell is produced in the usual manner by being prepared and treated as, for ordinary, backing, and is placed in the backing pan. 7 This pan containing the;- prepare shell is swung into the melting potandallowed to fioaton' the molten metal therein until the solder melts,-when enouh metal is poured over to cover to shell, t e ed es used for the pan and"..allowedto come tothe same temperature as the saidpan'containing the prepared, shelL- While this platen,-.co ver or closure is heating allow the nietalto flow directly into the pan onto and over the shell covering the shell and risin to the -top'of the rn'ns'of the pan byrligting or raising .the pump handle. This -handle raises the piston above. the inlet. conin the other kettle is lifted. out of the pot p or' kette-and swung into place with its unnecting the pump cylinder with theinside of. the melting potor kettle and as long as' this is'tonis above the inlet the metal runs or ows directly-from the pot or kettle through the inlet into .the pump cylinder or chamber, then through t e outlet pipe intothe'backing'p'an'.

The platen, cover or closure having .-.become heatedto the temperature of the metal de'r sideir'esting on the rims of the pan thus formihgpficlosd box, "It is secured by a handwheel, screw, or by clamps or other suitablejmeans. The pan having been filled I withj-irietalas shown, a vent place'd' inone sid e'ofthe platen, cover-or closure, is closed by a plug .inanipulated by a lever. Thepump plunger isjthe'n forced down into the cylinder or chamber, which closesthe inlet I 'intotheum .andforces whatmetal thereis in the 0 am r under' the'pistoninto. the pan. 'In this manner an. extra; amount. of pressureis broughtagainst the. shell "forcing ever part'of its surface against the pan. A best ofair isnow directed.

- the backin pan and its cover or closure may be change as desired. The box or pan may be made curved or semi-circular. Although I impart pressure to a stream of molten metal being transmitted to a backin pan or other. receptacle, which 'is preferab y closed "by a cover. or other means, et-an open backing pan or receptacle mayge say, without a cover or closure, I also may 'use a box 0;: pan. having a cover or removable side but open at the end.
